This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
If I want to marshall a class to XML, and that class contains a reference to another class, how do I ONLY put the ID of that subclass in the XML. My simple example of this appears below. Say I have 2 classes, Employee & Department:
What is the best marshalling program in Spring to do this (JAXB, Castor, etc), and how do I do this? Does this have a name so that I can google for more information about it? Also, I would need to unmarshall the XML back to java, such that I get an employee with a reference to a department, but only the ID of the department would be filled.
